Yes this. If I want to I can kick every Republican or MAGA hat out of my cafe with no legal risk. But I can't kick them out because they are Christian / Muslim or Black / White or Gay / Straight. Some of these things are considered to be outside of the control of the individual. They are innate. You can't choose if you're white or gay or to some degree Christian. If you're thinking that the religious exception feels weird given the rest on the list, I'd agree. But at the same time religious indoctrination in childhood when a child has literally no recourse but to follow what their parents say puts them at a major disadvantage to coming to terms with reality. If I acknowledge that a fundamentalist Christian growing up in the US would be just as likely to be a fundamentalist Muslim were they born in a different country really puts into question the "choice" aspect of religion. Some folks manage to escape it, but for most the social and cultural aspects and risk of ostracization keep them in the fold.
